Methyl-CpG-binding domain protein 1 is a protein that in humans is encoded by the MBD1 gene. The protein encoded by MBD1 binds to methylated sequences in DNA, and thereby influences transcription. It binds to a variety of methylated sequences, and appears to mediate repression of gene expression. It has been shown to play a role in chromatin modification through interaction with the histone H3K9 methyltransferase SETDB1. H3K9me3 is a repressive modification.

universally accepted notation uses the Roman characters G, C, A, and T, to represent the four nucleotides commonly found in DNA

Nullomers are short sequences of DNA that do not occur in the genome of a species (for example, humans), even though they are theoretically possible. Nullomers must be under selective pressure - for example, they may be toxic to the cell. Some nullomers have been shown to be useful to treat leukemia, breast, and prostate cancer. They are not useful in healthy cells because normal cells adapt and become immune to them. Nullomers are also being developed for use as DNA tags to prevent cross contamination when analyzing crime scene material.

thumb|500px|Schematic representation of factors promoting R-loop formation and stabilization An R-loop is a three-stranded nucleic acid structure, composed of a DNA:RNA hybrid and the associated non-template single-stranded DNA. R-loops may be formed in a variety of circumstances and may be tolerated or cleared by cellular components. The term "R-loop" was given to reflect the similarity of these structures to D-loops; the "R" in this case represents the involvement of an RNA moiety.
